Tube amp (Trace Elliot Hexa Valve) slowly going silent after 30 mins

Just give your tech a accurate and complete, detailed list of symptoms. Don't tell him how to fix it or what you THINK is the problem. Often, doing this results in a higher bill and rolling eyes.

No need to be cynical towards or about other forum members guys.
We all have the same hobby but everyone has their own insights depending on their experience. Not every answer will be the same and the TS (me) can pick bits of information from the several useful answers.

My wage comes in later this week (spent too much on my new car last month) and I will contact a tech in Amsterdam to see if he can help me.

I will use the input from this forum and my experiences with the amp to inform him about the problem. It indeed seems to be some small problem inside the pre section, in between the instrument input jack and the 12 band EQ.

if memory serves, that's a couple of sq inches worth of pcb.

Fixed it a while back. Switch of the mute circuit was just dirty. Hitting mute on/off a couple of dozens of times dealt with that.
There's still a little 50hz buzzing going on so she's probably gonna go to a qualified tech soonish after all.

Trust Andy on that. I've seen it before.
